Official 380 Thread

Is there a second amplifier for the radio for the speakers out in the cockpit? My radio works fine in the cabin but I get nothing out back. I just had the boat detailed and I found out that the hosed the entire cockpit down before the waxed it and Im afraid they got something wet that they shouldn't have. Tim
 
Could you just have the fader turned only to "FRONT?"
 
Good question but no, I wish it was that easy. And the selector by the cabin door is also switched on as well. I went so far as to take out the selector switch and checked it out and then I pulled the head unit out and checked it. Everything looks to be in order. When I switch the speaker wires from the cabin to the cockpit I still get nothing :(
 
OK. I don't know the answer to your question about a separate amp. But I'm going to watch to see if anyone else chimes in. Good luck!
 
On the '03, the only amps were behind the top right hand sofa back. You pull the seating surface out, the top comes straight up. Behind it, on the wall, are all the amps. There wasn't an amp in either the engine bay or the rear area.
 
I can't seem to figure out how to get the RAYNAV 300 GPS W/WAAS SENSOR to work. It comes on and all BUT most everything like the depth gauge and speed doesn't work. I have to rely on the Smartcraft for depth and that doesn't register when the engines are off... Any ideas?

What would be the best cruising RPM's for the most efficient gas milage ?

I will go with Rondds, pretty much. We typically cruise at 3400-3500RPM and adjust tabs for sea state. I think the 8.1L V8's like to be run, and not idled about.
If big seas slow us down to trawler speed, the fuel economy goes up. AT 19-20 knots(3400RPM) we burn just under 33GPH, at 7-8 knots (1500-1600RPM) we are under 10GPH.
If you do have to run slow because of conditions, or to avoid spilling drinks, try to find way to run up on plane, for at least 4-5 minutes, before going into the Marina or anchorage.
Similar to the need to run your car on the freeway occasionally, marine engines are happier if you run them hard enough to clean up the plugs and get the exhaust up to full operating temperature, before you park the boat.
 
Thanks guys, I agree in the fact that the engines want to run.

Not withstanding the wisdom of 'Pseudomind', or his recommendation on the subject, our Ray Marine was giving me fits when we took ownership of our 380DA. The problem was similar in that SOMETIMES it would not turn on, with out a bunch of button pushing, and an Indian rain dance. If I took it out and disconnected he power, Ta Da! it worked fine again. Our local tech suggested I might try wiring it so it always had power, even when the switches were 'off'. Thinking along those lines, I noticed when I turned off all the NAV switches, the unit gave me an alarm about 'no sonar signal' which I assume means it lost the Radar, or GPS input (We do not have sonar). If I then just turn of the RayMarine unit, all is lost without rain dance, and button pushing, or disconnecting power. What I found is if I shut off the switches, wait for the alarm, hit the power button to kill the alarm, and then hit the power button again for the OFF count down, everything is peachy. It may seem like voodoo magic, but I think there is a processing card that is easy to confuse, and holds the settings you last used. Once (with guests on board) I got it to work by hitting the "clear" button numerous times and repeating most of the swear words I know. Apparently was very entertaining. Took a while to live that down.

I'm wondering if a switch or something isn't working. I'm assuming it's the GPS unit mounted up on the radar arch? Here's a picture of the panel when we first bought the boat and was driving it away from the sales dock in March. It appears to be working some. I have the Autopilot and Electronics switch on. I pretty much just use the AP for rudder position.

This is different unit than ours, but the control buttons look very similar. I will bet the problem is in the multifunction 'power' switch on the GPS. Our Raymarine Chart Plotter has worked famously, ever since I figured out how to turn it off 'properly'.
 
OK I have a 1999 340 da now and wanting to move up to a 380. Looking at 01 and 02 , anything you would do differently? Different years? They pretty much have the same layout as mine but bigger. Thanks for the input guys.
 
I wouldn't do anything differently. If you see any 2001s with 7.4s move on to the next. I would strongly advise that you get one with 8.1s.
 
I agree that is one thing that is a must. How is it getting on plane with full fuel load and guest?

I would agree the 8.1's or the diesel version. As with any boat purchase, get a survey. On the Sea Trial run the generator, AC units, refrigerator, icemaker, windless, running lights, and every damn thing that has a switch. Be sure you know what works and what does not work. We love our 380DA.You will appreciate the improved engine access, and the V-Berth pocket door. If you run in any kind of sea, you will be surprised on the difference in ride. Get the Camper Canvass.

Our 380DA has the 8.1's and we have friends with a 340DA that has the the 7.4s (in fact that boat was part of the inspiration for us to move to the 'Dark Side'). On flat water the 340DA is faster, and comes up on plane quicker, but both those advantages start diminishing with wind and chop. I think the 380DA is more responsive to her trim tabs. We have had no problem getting up on plane with full fuel, full water, and 8-10 people on board. Typically will hold comfortably at 19-20Knots turning 3400-3500 RPM Burning 33GPH. Basically the 8.1L is a 'stroker'. Because it builds the same 'power' with increase cubic inches (and a milder cam) it sacrifices some top end for better low end torque. For us old sailors, 20 Knots is hauling butt. Get a little push from a flood tide and you can see 25knots on your Chart Plotter! (See youtube link at top).
Wee Ha!
